UPA1E272MHD

The UPA1E272MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPA series, engineered for high-reliability power applications. It provides 2.7 mF (2700 µF) capacitance at 25 V in a compact φ12.5 × 35.5 mm can, making it suitable for switching power supplies and general-purpose power filtering where compact size, high ripple capability and long life are required.

Designed for demanding thermal and ripple environments, the part combines low impedance, elevated ripple current ratings and a long endurance specification of 5000 hours at 105°C to support robust DC‑DC conversion and bulk energy storage tasks.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) rated at 25 V with capacitance tolerance ±20% (–20% ~ 20%).
• Low Impedance — Rated impedance of 32 mΩ, supporting low-loss energy storage and transient suppression in power rails.
• High Ripple Current — Low-frequency ripple current 2.499 A at 120 Hz and high-frequency ripple current 2.94 A at 10 kHz, enabling higher ripple handling across common switching frequencies.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.16 measured at 20°C, 120 Hz and 25 V, indicating controlled dielectric loss for power applications.
• Wide Temperature Range & Endurance — Operates from –55°C to 105°C with a rated life of 5000 hours at 105°C under specified conditions.
• Mechanical & Mounting — Radial lead, polarized can package with φ12.5 mm diameter and 35.5 mm length (lead spacing 5.0 mm). Supplied in bulk or bag packing (no terminal forming).
• Leakage — Specified leakage current of 2025 µA under stated conditions.
• RoHS Compliant — Meets RoHS requirements as indicated in the product data.

Typical Applications

• Switching Power Supplies: Bulk smoothing and decoupling for DC‑DC converters and SMPS designs that demand compact, high-ripple capacitors.
• Power Filtering for Industrial Electronics: Energy storage and ripple suppression in industrial power modules and control systems operating across wide temperature ranges.
• Telecom and Power Distribution Modules: Bulk capacitance for intermediate storage and transient damping where sustained ripple current and long life are required.
• General-Purpose Power Decoupling: Smoothing and transient support on board-level power rails in embedded and consumer equipment labeled for general-purpose use.

Unique Advantages

• High Bulk Capacitance in a Small Footprint: 2700 µF in a φ12.5 × 35.5 mm can provides substantial energy storage while conserving board space.
• Robust Ripple Performance: High ripple current ratings at both low and high frequency reduce thermal stress and improve reliability in switching environments.
• Low Electrical Losses: 32 mΩ impedance and tan δ = 0.16 (20°C, 120 Hz, 25 V) help minimize voltage drop and heat generation under load.
• Designed for Elevated Temperatures: 5000-hour endurance at 105°C supports long-term stability in high-temperature applications.
• Radial-Lead Convenience: Standard radial lead form and 5.0 mm lead spacing simplify through-hole assembly and prototyping workflows.
• Regulatory Compliance: RoHS compliance supports deployment in regions and products requiring restricted-substance conformance.
